Dear Sir I beg your pardon When we check free fall height of hammer 380+_ 5 mm that time mould should be filled with aggregate and top of the aggregate surface height should be measured
As per IS 383 - 2016 , There is only one limit for AIV for all concrete work in India 45 % except wearing course i.e runaway , spillway , road pavement , tunnel lining carrying water 30%.
Thank you sir. Very nice video, but sir if the height of free fall of the hammer is less than the prescribed value, what will be the effect on test result ?
@@HIGHWAYGUIDE absolutely right...qki jitna paas se hammer use karenge...agg. utna hi kam broke hoga ...jisse 2.36 sieve passing fraction ki value kam aaygi...to jaahir si baat hai...impact value bhi km aaygi
As per IS 383 - 2016 , There is only one limit for AIV for all concrete work in India 45 % except wearing course i.e runaway , spillway , road pavement , tunnel lining carrying water 30%.
AIV test dekhne ke baad mujhe lag rha hai...impact value kam honi chahiye...kya mai sahi hu...pls bataye... aur ha tolerance bata dijiye pls....for good concrete
Impact load means suddenly apply load And crushing strength means gredualy apply load. Impact value test use for highway construction which have impact load from wheels. And crushing value is useful in foundation column and other structures
sr ye dono cylinder k dia alag alag hai small wale ka 75mm or jisme test perform karte hai uska 102 mm yadi ham testing cylinder dia.102 mm usme direct sample ko 3 layer me fill kare 25 blows k sath ,,fir test perform kare ,,,,ye thik rahega ya ni ..
Practically there will be no difference , can do but how you take weight and it will be difficult to keep fall 380+/- 5 mm.As per contract in your project or any project we had to follow Indian standard.
Thanks a lot sir
I have missed my transportation lab class but after watching this i am prepare for viva
Thanks a lot
All the best
Legends watch 1 hour before practical exams😀😀😀
❤️
Same condition 😂😂😂
🫡
You are right.. mere practical hone wala h after one hour 🤦😅😅
Ultra legend see on site during job before performing 🙂

I beg your pardon

Sir plz tell imapact value of aggregate higher percentage better or lower?
Thanks sir🙏
Tq sar nice video
Very helpfull sir... Thanks a lot.... But range bta dijie value ka

👍👍👍
Nice
Good sir
sir good video but you don't minstion minimum % maximum
for example ; result is minmum 5% to 11%
For other than wearing course , it is 45%.
Good and must question
Thank you sir 🙏
Most welcome
1/2 inch passing and 3/8 retained?
Veri nice sir
Very nice demonstration with sound explanation......👏👏👍👍💐

Thank you sir. Very nice video, but sir if the height of free fall of the hammer is less than the prescribed value, what will be the effect on test result ?
Aggregate Impact value will be less
@@HIGHWAYGUIDE Thank you sir.
@@HIGHWAYGUIDE absolutely right...qki jitna paas se hammer use karenge...agg. utna hi kam broke hoga ...jisse 2.36 sieve passing fraction ki value kam aaygi...to jaahir si baat hai...impact value bhi km aaygi
धन्यवाद सर!
Super sar
Sr mera 1 question hai jo blows de rhe 15 times uska weight kitna hoga
Wow Exeliant sir 5*

Apko test ke sath details mai limit batana chahiye road mai kitna lete hai Building mai kitna lete hai bridge, railway, tunnel, dam etc.

AIV test dekhne ke baad mujhe lag rha hai...impact value kam honi chahiye...kya mai sahi hu...pls bataye...
aur ha tolerance bata dijiye pls....for good concrete
Sir what's difference between aggregate crush value and impact value.
If anybody knows pls reply
U don't need to do LAV if u do AIV. They are pretty much same. Nowadays LAV is obsolete.
Impact load means suddenly apply load
And crushing strength means gredualy apply load.
Impact value test use for highway construction which have impact load from wheels.
And crushing value is useful in foundation column and other structures

Sir ,what is permissible limit of percentage beyond which test must be repeated?
Other than wearing course , it is 45%.
Mja aa gya sir
very nice vedio sir
Thank you for your valuable comment.
@@HIGHWAYGUIDE in 10 mm aggregate sometimes we will not get any retained on 10 mm sieve in this case what we can do?
Thankyou sir 👍👍❤️
Thank you very much
I understand the how to do aggregate impact test clearly.. But what is use of that aggregate impact value...?
The main aim of this test is To determine the impact value of the aggregates used in pavement construction(Road

Sir AIV apparatus ki height ka calibration cup m agg dal kr krege Ya Fir empty cup se
After putting aggregate
sampling is done in wrong way.Can we sample from single place?
But sir....please let me know , what should be value of AIV .pls
sr ye dono cylinder k dia alag alag hai
small wale ka 75mm or jisme test perform karte hai uska 102 mm
yadi ham testing cylinder dia.102 mm usme direct sample ko 3 layer me fill kare 25 blows k sath ,,fir test perform kare ,,,,ye thik rahega ya ni ..
Practically there will be no difference , can do but how you take weight and it will be difficult to keep fall 380+/- 5 mm.As per contract in your project or any project we had to follow Indian standard.
Sir will the size of the aggregate taken for the sample remain same for Water bound macadam...passing 12.5 and retain on 10mm?
Yes
